“…Before phosphate adsorption, the basal spacing of LIG containing Cl − was 0.769 nm (Fig. 3A), which is consistent with the value previously reported [9,10,33]. After reacting with phosphate, the basal spacing of the adsorbent at either pH value shifted to 0.831 nm.…”

“…This material is synthesized through LiCl intercalation of gibbsite (␣-Al(OH) 3 ) or polymorphs and has a chemical formula [LiAl 2 (OH) 6 ]Cl·xH 2 O [9][10][11][12]. Gibbsite has been recognized as an important adsorbent for phosphate in soils and sediments [13][14][15].…”

“…9b-9d, revealing the presence of lithium, oxygen and aluminum. Tables II and III, it was evident that the characterization of the crystal structure is not conclusive since the measured lattice parameters in this study could not distinguish between the lithium-aluminum-carbonate-hydroxide hydrate version of hydrotalcite, 49,63 α-LiAlO 2 61,62 and Al(OH) 3 .…”

An investigation into corrosion inhibition properties of a primer coating containing lithium carbonate as corrosion inhibitive pigment for AA2024 aluminum alloy was conducted. It was found that, during neutral salt spray exposure, a protective film of about 0.2 to 1.5 μm thickness formed within the area where an artificial defect was introduced by scribing through the coating to the base alloy. This film showed a multilayered structure consisting of a relatively compact layer near the alloy substrate, a porous middle layer and a columnar outer layer. The thicknesses of the layers varied, as a consequence of the difference in the local concentration of lithium species leaching from the primer coating. The presence of the film in the scribed area significantly reduced corrosion of the alloy, with little consumption of the metal substrate within the scribed area during neutral salt spray exposure. Furthermore, the presence of the protective film resulted in a significant increase of impedance modulus, measured after the salt spray exposure.

“…[76][77][78][79][80] However, studies progressively reported the inhibitive character of Li when exposed to Al, particularly in alkaline environments. [81][82][83] It was suggested that Li was readily intercalated into the Al hydroxide matrix, 84,85 hence stabilizing the passive film when exposed to an aggressive environment. 81,86 On the other hand, Buchheit et al reported the formation of Al-Li layered double hydroxide (LDH) during the anodic dissolution of an Al-Cu-Li containing alloy.…”

The ubiquitous use of chromium and its derivatives as corrosion preventative compounds accelerated rapidly after the second industrial revolution, with such compounds now integral to modern society. However, the detrimental impact of chromium compounds on the environment and human health has prompted the need to revisit the majority of current industrial corrosion protection measures. This review retraces the origins of chromium replacement motivations, introducing the various legislative actions aimed at diminishing the use of chromium compounds, and critically reviews alternative corrosion preventative technologies developed in the recent decades to now. The review, herein, is intended for a broad audience in order to provide a concise update to an increasingly timely issue.
